MOTOR FOR STREET-CARS.

SPECIFICATION forming part of Letters Patent No. 409,115, dated August 13, 1889.

Application filed February 25, 1889. Serial No. 301,003. (No model.)

To aZZ whom it may concern.-

Be it known that I, WILLIAM I-I. PATTON, residing at Englewood, in the county of Cook and State of Illinois, and a citizen of the United States, have invented certain new and useful Improvements in Motors for Street- Cars, of which the following is a speciiication, reference being had to the accompanying drawings, in Which- Figure 1 is a side elevation, partly in section, on line l1 of Fig. 2. Fig. 2 is a plan view. Fig. 3 is a plan view of the parts remaining when the iioor with the parts mounted thereon is removed.

The obj ect of this invention is to improve the construction of the motor shown in Patent No. 377,081, dated November 29, 1887, and to adapt it to a greater variety ot movements and uses.

The nature and extent of my improvements will be pointed out in the claims.

The bottom A of the motor-car is made of framing and covered with a iioor in the usual manner, and any suitable superstructure or housing maybe mounted thereon for the protection of the operator and the machinery. The body or framing ot the car is mounted on the Wheels and axles B by suitable hangers or supports in the usual manner, and these Wheels are to run on suit-able rails C. Beneath this frame-Work there is mounted upon or supported by the axles a sub-frame D, which is best made of iron', and, if desired, this lower frame D may have additional supports from the frame A. On the sub-frame D are mounted the bearings of all of the movable shafts, as shown in Figs. l and 3. The side bars of the frame are provided With Hanges, as shown at lo in Fig. l, which project into corresponding grooves in the movable bearings to hold them in place. These movable bearings at one end are connected together by the bars E and at the opposite end by the bars F, so that they practically form secondary or movable frames mounted on the sub-frame D. The axles of the carrying-Wheels are provided with friction-pulleys G, which are driven by the friction-pulleys H H I I', according as either one is brought into driving contact with either of the friction-pulleys G, substantially in the vmanner set forth inl the patent. above referred to.

wise movement by means of the levers U V and connections, so as to be under the control of the driver or operator. The lever U is connected, by means of the link or rod X, With the lever or crank-arm d and rock-shaft e, which is provided with an arm f, which is in turn connected by the link g with the frame F, and at j with a cross-bar which is connected with or forms a part of the trame. The lever V is connected by the rod or link Y with an arm l) on the rock-shaft c, which rock-shaft is provided with an arm 7L, which in turn is connected by a link or rod c' to a similar connection j on the cross-bar of the frame E. The rock-shafts c e are supported in hangers a., which are attached to the frame A, and in practice it will be found advantageous to duplicate the arms f 7L and the links gi and locate them near the sides of t-he frames E F, so as to give these frames a more perfect movement with a less liability to bind on their supporting-frame D.

The levers U V are provided with ordinary locking-parvis engaging with metal racks WV, provided with suitable notches to hold either of the levers in any-position in which they may be adjusted.

It will be observed that the driving-pulleys H I inthe frame F are larger than the driving-pulleys H I in the frame E, so thatwhen either of the driving-pulleys H or I is thrown into driving-connection the car will have a faster movement than when either of the pulleys II or I are put in driving-connection, and the lever arrangements are such that either one of the four drivin g-pulleys may be put into driving contact at the Will of the operator. The driving-pulleyIis shown in driving-connection in Fig. 3, which of course carries the driving-pulleyI-I out of Working contact, while the pulleys Il I are so adjusted that both are out of drivingcontact; and it will be understood that when either of the pulleys H or I is in driving contact both of the pulleys H and I will be so adjusted as to be out of driving contact.

The shittin g of the driving-pulleys into and The sliding trames E F are given an end- IOO ou-t of contact for the purpose et reversing` the movement of the car, as explained in my former patent, while in this motor I have applied a second set of smaller driving-rollers, so as to be able to vary the speed ot the motor without changing' the operation er movements of the power used for revolving these pulleys. This arrangement for changing the speed of the motor is important, as dilterent rates of speed are frequently desirable, and for ascending grades the use of smaller drivingpulleys gives increased power with less speed, which is also desirable.

The driving mechanism is mounted on the framing or platform A, and, as shown, it consists of a gas-engine K, mounted on asuitable support J, which engine is provided with inductioirports and valves at N, which are operated by the eccentric-rod O, and exhaustports and valves at Il, which arc operated by the eccentric-rod P, and the exhaust is carried away bythe pipe M and discharged into the exhaust-box J from which the exhaust is discharged by any suitable pipe extended to the top of the ear or cab. The details of the gasengine are not specifically shown or stated, as the form shown is a common form, and I do not limit myself to any special form or kind of engine.

The gas may be carried in any suitable tank; but in the form shown I propose to generate gas or vapor from gasoline or other hydrocarbon oil, which maybe carried in the small tank located at Z and connected by a suitable pipe with the valve-chest N. The heat of the engine will be sufficient to convert the gasoline into gas or vapor suitable for driving` the engine after it has been in operation but a short time, and for the purpose of starting a separate heater or vaporizer may be applied. This part of the apparatus is not shown, as it forms no part of my invention.

The engine is provided with a water-jacket for cooling' it, and the water is carried in the tank S and is delivered from this tank to the jacket by a connecting-pipe near the iioor, (not showin) and thel water as it becomes warmed or heated is carried from the jacket and returned to the tank bythe pipe T. This method may be used for keeping the engine cool, or any other suitable method. may be adopted, as may be found most convenient.

The usual piston-rod is connected with the crank-shaft, and the crankshaft is provided with the ordinary balance-wheel R. It is also provided with the driving-wheels 1 and 7, as shown in Fig. 2, and the power is connnunicated from these drivingavhcels by means of wire ropes 1.7 and 18, which ropes, as shown, are carried four times around each wheel in each set ot driving-gears, and the number of turns may be varied to suit circumstances and to furnish the necessary amount of driving-power, and, as understood, these drivingropes are designed to be run continuously in one direction. The rope 17 in moving passes around the wheel 2, then around the idler il to the wheel 4., and back to the wheel l. One of the strands or sections of the rope passes ovel the tightener-wheel 5 and under the wheel (i, which returns it to the line ol the other strands or sections. The rope is continuous, and it will be understood that in moving it is crossed over, as shown at Fig. 2.

A tightener for one strand is sutiieient. This tightener is formed by mounting the wheels and G or l1. and 12 upon the fork l5, upon the ends of which the wheels are journaled, and the fork rotates in a shaft mounted upon and supported bythe frame 1G. The tightencr for 11 and 12 has its tension adj usted and supported by the spring 13 and the tightener for 5 and t5 by the spring 1l.

The rope 18 passes around the wheels S, D, and 10 in a manner similar to that of the rope 17. These ropes move lightly when the frietion drivewhecls are both out of gear, so that there is no special loss ot' power in running both sets at the same time, and when both sets are ruiming the driver can change the direction of the car or change the speed at will and almost instantaneously, thus making a complete motor variable as to the speed and direction of its movements, while the initial power is constant and the driving-ropes move continuously in the same direction, thus making the motor complete in all of its movements and givingit all of the motions and speeds required for operating passenger-cars or trains of cars in the streets of cities or towns and over tracks varyin largely in their grades.

I have shown and described the belt as a wire rope; but other wellsknown forinsoi rope or cable may be used.

"What I claim as new, and desire to secure by Letters Patent, is

1. In a street-ear motor constructed sub stantially as described, the combination of two systems of driving-gear connected with separate axles or trucks adapted to propel the motor-car at different rates of speed and in either direction from either axle by a single engine, substantially as specified.

2. The sub-frame I), in combination with the sliding frames E and F, each carryin sep arate driving-pulleys of a different size, substantially as deseri bed.

3. The combination of the rope or belt 217, wheels l, il, 3, and i, and sliding frame E with the Crank-shaft Q, rope or belt 1S, and wheels 7, S, i), and 10, and sliding frame l?, whereby the motive power may be operated continu ously in one direction and the car moved in either direction with varying rates of speed, substantially as specilled.

i. rlhe rock-shaft c, having the arms (l j", one or more link-rods q, and sliding trame F, with the link-rod X and hand-lever U, substantially as specified.
